Apple yesterday released the program for the 2008 WWDC Sessions and Labs. One lab, entitled Enhancing Your iPhone Web Application with CSS Transforms and Animations sticks out. The description:

Adding rich, hardware-accelerated graphics to your web content is now as easy as writing a few lines of CSS and JavaScript. Using the latest web standards, you can scale, rotate, or skew HTML elements, position page components within three-dimensional space, provide smooth transitions, and create captivating animations.

Very exciting. The problem is that the current Mobile Safari Browser doesn't support CSS Transforms and Animations. In fact, Apple's regular Safari was only able to support these features with a recent 3.1 release. Webkit betas have supported this functionality since late last year. This means that Apple will likely update the Mobile Safari browser in the upcoming weeks/months using a more recent Webkit engine.

Hopefully other Webkit improvements like speed increases and support for downloadable fonts also make it into the new mobile browser (without any security issues). A likely timeframe for the release would be alongside the iPhone 2.0 OS release in June.
